How is Mozilla doing you ask? Firefox VCS has completed the move from their own infra to checks notes oh yeah, GitHub dot com
@eloy @linus This feels like the logical next step after they were planning to move away from IRC, and "Discord" was a serious candidate in the running...
The rationale back then was something along the lines of "running our own comms is not our core business and we just want something that requires no effort to keep running" and that was pretty much already the point where Mozilla was dead to me, because clearly they were unwilling to build the kind of world they claimed to want to see.
I might expect that kind of answer from a tech corporation. It has no place in an organization that ostensibly exists for activist purposes.
